[QUERY] Notification Hub only working on Android

[StephanRaab]

Query/Question
I have an Azure function that talks to Notification hub.
When I post a notification message to the function it sends it to Notification Hub, which in turn sends it down to the device.
I'm only receiving notifications on Android in this manner.
But, when I go to Notification Hub and send a test message to iOS, I do receive that.

Setup (please complete the following information if applicable):

• OS: iOS 10.15.7
• IDE : Visual Studio Mac 2019
• Azure.NotificationHubs.Client.Xamarin v 1.0.0

I'm able to receive messages on iOS when deploying directly to an iPhone, but not when I archive the app and distribute via TestFlight. Notification Hubs shows the test message was successfully sent, but my remote notification listener delegate is not invoked.

iOS use two push notifications certificates
Production => for release purpose (Testflight, AppStore)
Sandbox => for debug purpose (development)

What is your configuration in notification hub?
